- * Ependymins signatures *
- *************************
-
- Ependymins [1,2] are the predominant proteins in the cerebrospinal fluid (CSF)
- of teleost fish. They have been implicated in the neurochemistry of memory and
- neuronal regeneration. They are glycoproteins of about 200 amino acids that
- can bind calcium. Four cysteines are conserved that probably form disulfide
- bonds.
-
- We developed two signature patterns for ependymins. The first one corresponds
- to a well conserved region located between two conserved N-glycosylation sites
- and which include a conserved cysteine residue. The second pattern is located
- in the C-terminal section and also includes one of the conserved cysteines.

- -Consensus pattern: F-E-E-G-x-[LIVMF]-Y-[ED]-I-D-x(2)-N-[QE]-S-C-[RKH](2)
- [C may be involved in a disulfide bond]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
-
- -Consensus pattern: [QE]-[LIVM]-F-x(2)-P-[STA]-[FY]-C-[DE]-[GA]-[LIVM]-x(2)-
- [DE](2)
- [C may be involved in a disulfide bond]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
